OPERATING-TAB LE Specification of Letters Patent.

Patented Jan. 7, 1908.

Application filed March 19,1907. Serial No. 363.308.

To all whom "it may concern:

Be it known that I, JAMES HENRY DOWNEY, a citizen of the United States,residing at Gainesville, in the county of Hall and State of Georgia,have invented a new and useful Operating-Table, of which the followingis a specification.

This invention relates to surgical operating tables, and has for itsprincipal object to provide a device of very simple construction whichmay be adjusted to position for exercising traction force in anydirection in orthoedic work or for the purpose of reducing fractures ordislocations of the limbs or other parts of the body, and for holdingthe parts in place during bandaging or the application of any dressings,plaster of paris, or the like.

A further object of the invention is to provide a device of thischaracter in which the necessary pull may be exerted, and the partsfirmly held without danger of slip ing or relaxing until the operationis comp eted.

With these and other objects in view, as will more fully hereinafterappear, the inven tion consists in certain novel features of construetion and arrangement of parts, hereinafter fully described,illustrated in the accompanying. drawings, and particularly pointed outin the appended claims, it being understood that various changes in theform, proportions, size and minor details of the structure may be madewithout departing from the s irit or sacrificing any of the ad.-vantages o the invention.

In the accompanying drawings :Figure 1 is a perspective view of anoperating table constructed in accordance with the invention. Fig. 2 isa plan view of the same showing in dotted lines a number of positions towhich the various parts of the traction apparatus may be adjusted. Fig.3 is a side elevation of the table showing the position of the parts asadjusted for a direct upward pull. Fig. 4 is a detail sectional view ofa portion of the windlass or winding mechanism. Fig. 5 is a detail viewof one of the clamps. Fig. 6 is a detail sectional view of one of thetable sockets and clamps.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

The main frame of the table is referably formed of iron or steel rigid ybraced throughout, and including vertical, or approximately vertical,end members 10 and 11 and side rails 12. To the frame of the table issecured a post 15 carrying a seat 16, and the post further carries aclamp 17 which may be used to clamp and hold the pelvis in positionduring certain operations. The table is so arranged that the supportingsurface may remain perfectly horizontal, or its various parts may beadjusted for the purpose of inclining the back, or the leg and forholding any part of the body in a position most convenient for thesurgeon. ln the present instance each of the leg supports is formed oftwo sections 18 and 19, the section 19 being arranged to receive theupper part of the leg and the section 18 the lower part thereof, andthese sections are pivotally connected together in order that the limbmay be flexed as desired, and one or both sections may be dropped fromunder the limb or the back may be telescoped to give access to thepatient while dressing around fractures and various orthopedic cases.

The principal feature of the invention, however, is the tractionapparatus, and to receive this, the table is provided with four sockets20, 21, 22 and 23, there being one of such sockets at each corner of thetable. These sockets are arranged for the reception of a pair ofvertically disposed pins 25, which are held in place by cam lovers 26pivoted on the socket members, as shown in Fig. 6, for the purpose ofpreventing upward movement and displacement of the pins from the socket.

On the upper end of one of the pins 25 is pivoted a rod 28, said rodhaving a reverse bend at a point adjacent to its pivotal connection, sothat the body portion of the rod may, if necessary, be adjusted to apoint below the top of the table, and pivoted to the other pin 25 is arod 29, that is bent in a similar manner.

Near the outer end of the rod 28 is a sleeve 30 that is free to slide inthe direction of the .length of the rod, and said sleeve carries aclamping screw 31 by which it may be locked in any position ofadjustment. '1 his sleeve carries cars 32 to which is pivoted one end ofa tube 33, and the tube is telescoped on the rod 29 in order that thedistance between thesleeve 32 and the pivoted end of the rod 29 getherand thus forming in connection with the rod 28 an angular truss ofconsiderable strength and rigidity.

It will be seen that by loosening the screws 31 and 25, the angularrelation of the two arms of the frame may be varied to a considerableextent, so that the apex of the frame may be drawn to one or other sideof the longitudinal axis of the table, or may be maintained in suchaxial line as required, and when once adjusted, the frame may be lockedin place by turning the screws. This construction permits of aconsiderable range of adjustment in a horizontal plane, while thepivotal connections of the frame with the pins permits swingingadjustment in a vertioal plane, so that the frame may be moved to avertical position, or to any angle betv. een the vertical andhorizontal, or to some extent below the horizontal plane.

In order to firmly lock and hold the frame in adjusted position, abracing member is employed, this, in the present instance, comprising atelescopically fitting tube 38 carrying a collar 40 through whichextends a clamping screw 41 which may be turned tightly against the rod.The outer end of the tube 38 is pivotally connected to an ear projectingfrom a sleeve 42 which may be adjusted in the direction of the length ofthe rod 28, while the lower end of the rod 39 is pivoted on a pin 43,said pin being swiveled in a clamp 44 that is arranged to embrace anydesired part of the frame of the table, thus as show 11 in Fig. 1 theclamp may be firmly secured to the vertical leg 10 of the table, or asshown in Fig. 3 it may be secured to one of the horizontal bars 12.

On the outer end of the rod 28 is a block 50 which may be adjusted bothlongitudinally and circumferentially of the rod and locked in place by aclamping screw 52. On this block is pivoted a small frame 53 whichcarries a short shaft 54 on which is mounted a ratchet wheel 55 andwinding drum 56. Piv otally mounted on the end or ends of the shaft 54is an operating lever 58 carrying a pawl 59 arranged to engage the teethof the ratchet wheel, and the ratchet wheel is held from return movementby a small lock pawl 60 that is pivoted on the frame 53.

To the winding drum is secured one end of a flexible cord or chain 62which may be connected in any desired manner to the part on whichtraction force is to be exerted, and by operating the lever 38, the cordor chain 62 may be wound up and the limb or other part of the bodystretched to reduce the fracture or dislocation, or for any otherdesired pur pose.

The several sockets 20, 21, 22 and 23 are so arranged that the pivotpins may be placed in any of them, and the traction frame may thus bead'usted at either end or either side of the table, while theadjustability of the members of the frame permits the placing of the\TlllCllLSS at any point for the purpose of exercising a pulling strainin any direction.

When the parts are adjusted to the position shown in full lines in Fig.2, a straight out pull may be exerted in a direction at a right angle tothe longitudinal axis of the table, or if adjusted to the dotted lineposition a, a straight out pull may be exerted on the left arm of apatient, as for instance in the reduction of a fracture or dislocationof the radius, ulna, humerus. When adjusted to the osition shown bydotted lines I), in Fig. 2, ongitudinal strain may be exerted on thespine. When adjusted to the dotted line position 0 traction force may beexerted in the direction of the length of the right arm. The dotted lineposition d, Fig. 2, is exactly the opposite of that indicated in fulllines in thesame figure. The dotted line position 6 shows the adjustmentwhich will permit pulling strain on the right leg at a slight angle tothe longitudinal axis of the table. The remaining two dotted linepositions and 9 show adjustments which will permit direct pulls on bothlegs in a direction parallel to the length of the table.

hen the parts are adjusted to the position shown in Fig. 1, a slightupward pull in the direction of the length of the table may be exerted,and when the parts are moved to the position shown on Fig. 3, a directvertical pull may be obtained.

The slidable connections of the various parts permit of an almostindefinite number of adjustments, so that traction force may be exertedon practicallyany part of the body and in practically any direction, andwhen the bones have been brought into proper position they may be firmlyheld without danger of release or displacement during the ap plicationof any dressing or drying of plaster casts, etc.

The apparatus will further serve as a means for rigidly supporting thelimb or other part of the body during the temporary removal of portionsof the surface of the table, as for instance, the leg or back rest, sothat bandages may be readily wound around any part of the body Withoutthe necessity of lifting or moving the patient in any manner.
